The sash weights are tiny boxes, typically made of cast iron that serve to support the sash as well as help balance the counter-weight system of the window. They are located in the bottom rails of every window frame, and are covered by an access panel made of wood that can be cut open to reveal their position. These panels can also be removed to gain access to the pockets of sash weights for cleaning, repairs or replacement.

This can be caused by the weights being too heavy (they are supposed to be a bit heavier than the top sash) or due to them being installed incorrectly (some people disabled their weight systems by cutting them and taking them off to save money, or turning them into scrap metal).

This will keep the sash on its place while you finish stringing counterweights.
